A research team led by scientists from the University of Arizona have used the National Elevation Dataset produced by the U.S. Geological Survey to predict how sea level rises could affect coastal cities by 2100. This is the first such study to include every coastal city with a population above 50,000.
Based on projections that sea levels will rise about 1 metre by the end of the century, the analysis suggests the southern Atlantic and Gulf coasts could be particularly hard hit…
Miami, New Orleans, Tampa, Fla., and Virginia Beach, Va. could lose more than 10 percent of their land area by 2100.
The press release goes on to say predicted levels global warming could lock us into further sea level rises due to melting Greenland and Antarctic ice sheets…
By 6 meters (about 20 feet), about one-third of the land area in U.S. coastal cities could be affected.
The two maps depict both 1m (red) and 6m (yellow) scenarios. Above, covering the South-East coast, and a second for the cities of New Orleans, Virgina Beach, Miami, Tampa, New York and Washington.
Some interactive maps of the effects of sea-level rises are available on the UA Department of Geosciences Environmental Studies Laboratory site.
